As long a people respond, they will continue. They are crooks looking for uninformed people they can scam and rob! Tell everyone you know to avoid answering calls from unknown callers. If they don't have caller ID, tell them to be very wary of any caller they don't know. If they have an answering machine, let calls go there, and NEVER give out any private info.
OK it's good we have this forum, but how is it the same number has been used for almost a full year and it hasn't stopped???? Seems like the enforcement is totally inept!
